How it works

SonarQube is a standard tool in professional software teams. It supports many languages, tracks quality trends over time, and gives developers clear explanations of each issue and how to fix it. Its quality gates make code standards automatic: a pull request either passes the bar or it does not.

The Community edition is free and open source for self-hosting, while commercial editions add more languages, security features, and support, with pricing on the official site. It is a solid foundation for any team that wants code quality to be measured and enforced, not just hoped for.
